Sony Xperia Z2 D6502 no network issue start after 5.1 update.

Already done. Update by PCC. Repair by PCC.
make sure you are in an area of good signal.. try to check your network settings
settings>mobile networks>preferred network type ( try to set it to gsm only then set to your preferrence.)
check your network operators set it to auto.
Preffered Network - GSM Only = No Signal, Preffered Network - WCDMA Only = 1 or 2 / 3 Bar Signal. But in my Sony Xperia M4 Aqua, Preffered Network - GSM Only = Full Signal, Preffered Network - WCDMA Only = 2 or 3 Bar Signal.
